As long as Lightsail doesn't limit the capabilities of their VPS, I don't see why it would be any different from a normal install on Ubuntu.

That actually reminds me. Is anybody here a Guru of SEO? I'd love to talk to you. We have no idea if 302'ing try.* (the original subdomain) to community.* is better than doing a permanent redirect. What worries me is that sometimes I get links on google for try and not community. Anyways, we're not experts, so tell us please
